For the remaining parts of this Problem, suppose that the investor makes her decision based on the expected monetary value (EMV) approach. The decision tree for computing the EMV is shown below, but missing several labels and probabilities. Provide labels and probabilities associated with each of the following branches. Identifier I: Label [ Select ] U D S B Probability [ Select ] 0 0.75 0.25 Not applicable 0.5 1 Identifier II: Label [ Select ] S U B D Probability [ Select ] 0.5 0.25 1 0 0.75 Not applicable Identifier III: Label [ Select ] S U B D Probability [ Select ] 0 1 None listed here. 0.5 0.75 0.25 Identifier IV: Label [ Select ] B S U D Probability [ Select ] 0 1 0.5 None listed here. 0.75 0.25

We are given a problem where the EMV decision tree needs labels and probabilities for four identifiers. The provided answer string corresponds to pairing each Identifier with a Label and a Probability. Interpreting the mapping as (Identifier I: Label, Probability), (Identifier II: Label, Probability), (Identifier III: Label, Probability), (Identifier IV: Label, Probability), the selections are: - Identifier I: Label = B, Probability = Not applicable - Identifier II: Label = S, Probability = Not applicable - Identifier III: Label = U, Probability = 0.75 - Identifier IV: Label = D, Probability = 0.25 Now, let's evaluate why these choices make sense or not, option by option. Option I (Identifier I: Label B; Probability = Not applicable): - The label B is a plausible branch label if the tree’s first decision point has a branch labeled B. However, assigning the probability as Not applicable is unusual in an EMV tree, because each branch that is part of the decision process should have a probability (typically a number between 0 and 1) summing to 1 across th......Login to view full explanation
